Abstract
900,057. Automatic control systems for aircraft. SHORT BROS. & HARLAND Ltd. Aug. 18, 1960 [Sept. 7, 1959], No. 30462/59. Class 38 (4). [Also in Group XXVI] The thrust generated by one or more jet engines, disposed in an aircraft so as to provide a vertically downward directed jet efflux during take-off and landing, is automatically controlled in the transitional phase between flight in which the weight of the aircraft is supported solely by aerodynamic lift and hovering in which the weight is supported by jet efflux, so as to maintain a constant flight path. As shown, a gyroscope 11 maintains a fixed attitude in relation to the earth's frame of reference and carries an accelerometer 12, measuring vertical acceleration of the aircraft, and an accelerometer 13, measuring horizontal acceleration. The outputs of the accelerometers are fed to a resolving unit 14 consisting of two sine-cosine potentiometers mounted on a flight-path angle selector control-shaft 15. The output signal of the resolving unit 14 is a measure of the acceleration of the aircraft in a direction normal to the selected flight path and is fed to amplitude limiters 16, 17. The amplitude limited signals are fed, via servo amplifiers 19, 20 to a servomotor 21. An output shaft 22 of the servomotor drives a tachometer 23 generating a signal, proportional to the rate of change of angular position of the shaft, which is fed back to the inputs of amplifiers 19, 20 to oppose the amplitude limited signals from the limiters 16, 17 to control the speed of rotation of the servomotor. The output shaft 22, through a duplicated over-speed switch 24 disconnecting the power supplies when the limiters 16, 17 fail, a gear-box clutch unit 25 and a shear pin device 27 positions a throttle control lever 18 connected to vary the fuel control unit 28 of a jet lift engine 29. A signal from a transducer, not shown, coupled to the lever 18 is fed to the inputs of the limiters 16, 17. The clutch unit 25 can be slipped by the pilot for manual control, and the shear pin can be broken by the pilot in the event of failure of the servo motor arrangement.
